How to Use GitHub Copilot to Boost Code Review Speed in 2026

If you’ve ever been bogged down by code reviews, you’re not alone. Many of us have faced the tedious grind of sifting through lines of code, looking for bugs or suggesting improvements. But what if I told you that you could cut that time in half using GitHub Copilot? In this guide, I’ll walk you through how to leverage Copilot to supercharge your code review process in just 30 minutes.

Prerequisites: Get Set Up

Before diving in, make sure you have the following:

• GitHub Account: You need an active GitHub account.
• Access to GitHub Copilot: Either through a personal subscription or an organization that provides it. Pricing is currently $10/month for individuals or $19/month for teams.
• VS Code or JetBrains IDE: Copilot integrates seamlessly with these editors, so install one if you haven't already.

Step-by-Step Setup to Use GitHub Copilot for Code Reviews

1. Install GitHub Copilot

• Time Estimate: 5 minutes
• Instructions: Open your IDE, navigate to the extensions panel, and search for "GitHub Copilot." Click install and authenticate with your GitHub credentials.

2. Load Your Codebase

• Time Estimate: 5 minutes
• Open the repository you want to review. Ensure that the code is loaded in your IDE.

3. Start Reviewing Code with Copilot

• Time Estimate: 10 minutes
• Navigate to the files you want to review. For each function or segment of code, you can type comments like // Review this function and let Copilot suggest improvements or highlight potential bugs.

4. Use Copilot's Suggestions

• Time Estimate: 5 minutes
• As you type, Copilot will generate suggestions. Review these carefully. Accept useful changes with Tab or dismiss them.

5. Finalize Your Review

• Time Estimate: 5 minutes
• After going through the code, make your final notes or comments directly in the code review interface on GitHub. You can also use Copilot to generate summary comments if necessary.

Expected Outputs

By the end of this process, you should have:

• A significantly faster code review process.
• Suggestions and improvements directly integrated into the codebase.
• A clearer understanding of the code's functionality thanks to Copilot's insights.

Troubleshooting Common Issues

• Copilot Not Suggesting Anything: Ensure you’re writing comments or code that triggers suggestions. Sometimes, it needs a prompt.
• Inaccurate Suggestions: Remember that Copilot is a tool, not a replacement for human judgment. Always validate its suggestions.
• Performance Lag: If your IDE is slow, check if there are too many extensions running.

What's Next?

Once you’ve streamlined your code review process with Copilot, consider exploring other AI tools to further enhance your workflow. For instance, tools like CodeClimate can help with static analysis, while Snyk can assist in security reviews.
